Application: filed January 2i, 1925. Serial No.5 3,752. 7

This invention relates to automatic grain shockers secured to and operated by a grain binder. 3

The object of this invention is to-provide an automatic grain shocker' which is simple in operation and economicalin manufacture. A further object is to provide a grain shocker thatis light in weightand maybe easily secured t'o'orremoved from "the frame of an ordinary binder. I A further object is to provide an automatic; grain shocker that will deposit the shock'on the ground with the bottom spread and the.topl compressed. I I 'J A further objectis to provide a mechanism for shocking grain that will utilize the power of gravity foriturningthe bundles 'into vertical' position.

These and other obj'ects'will be apparent to those skilled'in'the art. 7

My invention consists in the construction, arrangement and combination of the various'parts of the device, whereby the objects contemplated' are attained "as hereinafter more fully set forth, pointed out'in my claims and illustrated'in' the accompanying drawings, in which: F

Fig. 7 is a sectional view of a part of the operating meansv employed to remove the shock from the platform' and deposit it on the ground. This showing is taken online 7-'7 of-Fig. 1.

My grain shocker is comparatively small and is designed to occupy the "position usually occupied by the bundle carrier.

I have designated the ordinary binder by the numeral 10 a portion of which is shown in Figures 1, 2 and 3. Secured to the binder This showing is taken on line by the bolts 11, 12, and 13, the strap iron '14. Pivotally attached to this member 14 Y the-bolts 15 and 16 is the frame 17 of my shocker. Rotatably mounted on a spindle 18 at one end of this frame is the platform 18. This platform is circular except for the cam lug-"wand the internal cam 20 on its periphery. Thenumeral 21 designates spurs on the top surface of the platform 18. The brackets -22 on the frame'17 support the rollers 23 which engage the under side of the platform 18 near itsperiphery. Slid- I ably mounted in the frame 17 and below the platform 18 is the rod f 24. Pivotally secured to one end of this rod'is the link 31 which is pivotally secured at its opposite end 'to'the crank arm 25 which is permanently secured to the shaft 26 of the binder needle 27. It will be noted here that if, the needle 27is actuated the rod 24 willalso be reciprocated." Permanently attached to this rod 24 is'the collar 28 which'supports the operating pawl 29." This "pawl is yieldingly retained 1n proper position by the spring 30 and is so positioned as to en a e one side of one of the-lugs 32, which'are sgaced apart in circular arrangement on'the under side of the platform 18. The numeral'33 designates a bracket on the frame' 17 Whichpivotally supports the spring detent 34. This detent engages one side of the lugs 32 and prevents back lash of the platform-18. Thenumera-l 35 designates a cam lug on the rod 24. slid"- ably mounted .in'the-frame 17 is the rod 36 which the roller 37 at one end. This roller is so positioned as to engage'the cam 35 when the rod 24 is actuated. Pivotally and slidably secured-to the other end of the rod 36 is theflever 38. This lever'is pivoted at 39 to the bracket 40 which is secured to the frame 17 by bol'ts. The other end of the-lever 381s pivotallyand slidingly se cured to the rod 41'which is slidably mounted in the slide bearing'42 of the bracket 40. I I

designates pins which engage one end of the springs and also limits themovement of the bars 44 to one direction. Slidably mounted in the frame 17 is the rod 47. Mounted on this rod and so positioned as to engage the bars 44 is the roller 48. In other words when the platform 18 is rotated 1/7 of a turn one of the bars 44 will engage the roller 48 at its inner end and will force the rod 47 toward the binder until the roller 48 has traveled over the face of the bar and past its pivot whereupon the bar 44 will trip and release the roller. At this stage the spring 49 will return the rod 47 to its original position-and ready for engagement with i the following bar. Pivotally secured to the end of this rod 47 is alink 50 which 1s pivotally secured at its other end to the lever 51, I This lever is pivotally secured at 52 to the binderlO. This lever is so bent as to travel when actuated in the slot 53 of the binder 10. At its free end is the spike 54.

The numeral 55 in Fig. 4 designates a dotted.

showing of a bundleof grain. The practical operation of this part of my invention is as follows: 7

After enough grain has been deposited at 56 the needle 27 moves forward to the knotter 57 andties the loose grain into a bundle in the ordinary way. By this operation the needle shaft 26 is rotated which in turn effects the arm'25 and pulls the rod 24 toward the binder. As the pawl is in engagement with one of the lugs 32, that lug will also be pulled toward the binder, thus rotating the platform 1/7 of a turn. By the rotating of this platform one of the bars 44 will engage the roller 48 of the rod 47 and will pull that rod forward until the bar 44 trips. By this operation the spike 54 will pierce the new made bundle 55 near its top and will carry it toward the platform. At the time of piercing the bundle 55 it is laying in horizontal position but as it is swung and suspended on the spike 54 near its top it will, by the power of gravity be turned into vertical position. The lever 51 moves on toward the platform and deposits the bundle on one of the spurs 21 nearest the center of the platform, At this stage the rod 24 is pulled forward and the cam lug will be engaging the roller 37 and the rod 41 will thereby be extended and will retain the bundle on the platform until the spike 54 is withdrawn from the bundle. This withdrawal is accomplished by the bar 44 tripping and allowing the spring 49 to return the rod 47 to normal position. At this time theneedle 27 of the binder returns to normal position and returns the rod 24to its original position, thereby allowing the spring 43 to return the spike 41. As the platform is rotated 1/7 of a turn the detent 34 engages another of the members 32 and prevents the platform from returning with the rod 24. By this operation the pawl 30 must slide over the next lug 32 which is beveled at one edge and engages it for the next action of the binder needle. The next bundle can not be deposited in the center dueto the fact that one already 00- cupies that position, therefore the spur 54 will swing the bundle-as near to the center as possible and will deposit the bundle beside the center one. As the platform turns 1/7 revolution each time the needle of the binder actuates; in one revolution of the platform there will be deposited on the plat- 7 form 7 bundles.

The rearwardly extending portion of the frame 17 I have designated by the numeral 58. This portion of the frame has two uprights 59 and 60 which have the shaft 61 journaled therein. At the end of this shaft Loosely mounted on the shaft 61 is theyoke bracket 68. Pivotally mounted on each end of this bracket are the arms 69 and 7 0. They are yieldably held in approximately parallel position by the springs 71 and 72. Securely mounted on the shaft 61 at the end furthest from the binder is the bevel gear 73 which engages a second bevel gear 74 mounted on the upright 60. This bevel gear engages a third bevel gearloosely mounted on the shaft 61. By this arrangement the last mentioned bevel gear turns to the right when the shaft 61 turns to the left. Mounted near the other end of the shaft 61 and permanently mounted thereon is the wheel 76 which has the inwardly extending lug 77. The numeral 78 designates a similar inwardly extending lug on the bevel gear 75. Pivotally mounted on the frame 58 is the lever 79 which carries at one endthe roller 80. This roller is held in. engagement with the periphery of the platform 18 at all times by the spring 81. The other end of this lever is forked and engages a peripheral groove 82 in the loosely mounted wheel 83 on the shaft 61. This wheel 83 is permanently secured to the member 68. The numerals 84 and 85 designate projections on the arms 70 and 69. Rotatably mounted on the arms 69 and 7 O are the gripping members 86 and 87 The numeral 88 designates teeth on these grippingmembersto facilitate these members in retaining the shock within their grasp. Rotatably mounted in the member 68 is the shaft 89. Secured to one end of this shaft is the drum 90 which has secured thereto the chains 91 and 92. These chains are attached at their opposite ends to the arms 69 and 70. At'the other positioned on opposite sides of the shaft 61f The numeral 97 designates -a caster wheel'olesigned to engage the ground and V to support the side of the frame 17.

' The practical operation of this 'last de scribed part of my invention is as follows:

After the platform 18 has made a complete revolution there are seven-bundles def posited thereon. At this time the cam lug 19 is in engagement with thetrollergSO WlllCllEtCt-Lltl't-BS the lever 79 and slides the bracket 68 and members carried thereby on the shaft 61 until the projection 85 engages the lug 78 on the bevel gear 75. I As the bevel gear is turning to the right it will carry the projection with it and thereby the arms 70 and 69 will rotate with the shaft 61 and will bedeposited on each side of the shock resting on the platform 18. By the above operation the pinion 93 will be in engagement wit-h the mutilated gear 94 which is turning with the shaft 61. This engagement rotates the drum and there by pulls the two arms 69 and 70 together and grips the shock between the members 86 and 87. As soon as this action is completed the roller 80 is in engagement with j These members Will retain this shock until b the proper moment for release'due to the fact that the complete mechanism of this part of my invention is traveling with the shaft-61 and the teeth of the pinion 93 will be in engagement with the gear 94 and will prevent the drum 90 from unwinding and allowing the arms 69 and 7 0 from spreading. As the members 86 and 87 grip the shock near its top and are pivotally mounted on the arms-69 and 70, the shock I for oscillation, springs for yieldingly holdwill always be in vertical position. By the time the shock is in proper positon above the ground the roller 80 is out of engage-- ment with the internal camQO and the lever 79 will release the pro ectlon 77 from the lug 76 and the gear 941-will travelon and out of engagement with the pinion 93,

thereby allowing the springs 71 and 72 to force the arms apart, unwind the drum. and deposit the shock on the ground. All these actions are properly timed so as to obtain new made bundle near one end so that when the desired results. The bracket 68 and members carriedthereon are'released from engagement-with the shaft -61 just'before reaching horizontal and thcreupon fall to 'Qitllfil the cushion spring 95 or 96'where they rest until the next operation.
